At its pivoted end, the chanthe members 20 permitconvenient removal and nel section of the. jaw 5v has its top and bottomreversal of these facing members on the jaws of flanges extended to formprojectingV tongues 8 the clamp. Thus either flange 2I or 22 of eitherwhich receive, between them, a pair of integral facing member may bedisposed along the inner 55%' sides of the jaws 5 and 6 for grippingcooperation with the hair, and after such use of one flange, the facingmember may be removed and reversed to present the other flange along theinner side of the jaw. The outer surfaces of the iianges 2| and 22 ofeach facing member may be ribbed or grooved as shown in Figure 1.

A heat insulating strip 25, of felt or other suitable material, issecured to the bottom of each of the facing members 2li preferably bymeans of parallel lines of stitching indicated at 25. Of course thesestrips 25 may be secured to the members 25 in any other suitable orpreferred manner. The strips 25 are substantially coextensive with thefacing members 20, and their opposite ends project endwise beyond themembers 20 to underlie substantially the entire length of each jaw 5 and5. The relatively flat form of the channel-shaped jaws 5, together withthe rounding of the upper and lower edges of the backs of these jaws,permit the facing members to be applied and removed sidewise and thenturned to the position shown, although the form and yieldability of themembers 2B will permit these members to be applied from the bottom anddirectly to the desired position and similarly removed.

Disposed within the channel sections of the jaws 5 and 5 are springs 28having intermediate portions 29 lying along the open inner sides of thejaws. The inturned ends 3l! of the springs 29 terminate in longitudinalextensions which are adapted to be sprung between and into interlockingengagement with prongs 32 pressed in from the back walls of the jaws 5and '5. The springing of the ends of the springs 28 between and intoengagement with the prongs 32 secures the springs 28 removably inposition within the jaws and bows the intermediate portions 29 outwardlyand places the same under tension. These bowed intermediate portions 29of the springs 28 press the inner side flanges of the facing members 25inwardly and provide an effective gripping action upon the bunchedstrand of hair placed between the jaws, as indicated at 34. The springs28 maintain an effective gripping action of the members 20 upon the hairat all times and increase the life of the members 20, particularly alongthe locations where the hair is gripped. And the life of these members29 is further increased by the reversibility of the same upon the jaws 5and 6.' The springs 23 preferably bow the inner sides of the facingmembers 20 to con- Vex form along the locations where the hair 34 isgripped, as shown at 35 in Figure 2.

The particular curler I3, selected for illustration, is ofthe type morefully disclosed in my prior patent, No. 1,862,721, patented June 14,1932. Suice it to say that this curler comprises the metal spool or reel35 of circular section, diminishing in diameter from its opposite endstoward the center, and a saddle-like retainer 31 pivoted to one end ofthe spool at 38. A iingerpiece 39 is provided at one end of the spoolfor turning the same, and the opposite end of the spool has teeth '46which cooperate with a spring pawl 42 to prevent unwinding of the spool.

The spring pawl 42 comprises a spring strip turned in beneath the bottomof the jaw 6 and secured thereto as by means of a rivet 43. A prong 44,struck in from the spring strip, engages the teeth and holds the spoolagainst unwinding. The upper end of the spring strip is rounded orturned at 45 to be actuated by the operators finger for the purpose ofreleasing the prong 44 from the teeth 4U. A small lug 46, integral withthe journal part IB, forms a stop for limiting the releasing action ofthe spring pawl.

The device for closing the jaws and locking the same in closed positioncomprises a lever pivoted for free swinging movement at one end at 5lbetween the tongues I4 of the jaw 5. The lever 5D comprises a pair ofsuperposed arched pieces between the pivoted ends of which a Washer 52is provided. A latch 53 is pivoted at 56 between the free ends of thearched pieces constituting the lever 5D, and this latch 53 preferablyhas a shoulder 54 which, by engagement with an integral stop 55 turneddown from the edge of the top piece of the lever 50, limits swingingmovement of the latch in a cl`o`ckwise direction with respect to thelever 50 as viewed in Figure 2. The pieces constituting the lever 50have lips 5U turned in, or the pieces are otherwise formed to bearagainst the latch member 53 to prevent free turning of the latch withrespect to the lever. As a result, the latch 53 and lever 5U swingsubstantially as a unit about the pivotalll connection at 5l with thejaw 5, and until the latch engages the other jaw, whereupon the latchand lever swing about their respective pivots, as will appear. The latch53 has a relatively short projecting nger 51 provided with a rounded camedge 58 which has a depression 59. 53 also has a finger-piece '60 turnedat substantially right angles to the pivoted part of the latch andpreferably elongated to give the operator a considerable mechanicaladvantage in closing and locking the device.

Further, to facilitate ease of operation of the device, the part on thejaw G for cooperation with the jaw closing and locking latch 53 is inthe form of a roller 62. This roller 62 is mounted between integraltongues 53 projecting endwise from the top and bottom flanges of thechannel section of the jaw 6 for free turning movement upon a pin 64 xedin the tongue B3 as by heading one end and riveting over the oppositeend of the pin.

With a bunch of hair between the jaws 5 and 6 as shown in Figure 2, thedevice is closed by applying the nger to the finger-piece 69 andpressing the same in the direction indicated by the arrow in Figure 2.This swings the latch 53 and lever 50 as a unit, or at leastsubstantially as a unit, about the pivot 5I until the finger 51 takesover the roller 62. Thereupon, as the ngerpiece is pressed further inthe same direction, the lever 50 continues its swinging movement in acounter-clockwise direction about the pivot 5l and, at the same time,the latch 53 swings in a counter-clockwise direction about the pivot 58.The resulting action gives the operator great mechanical advantage andforces the jaws 5 and 5 positively to closed position with great force.The roller action, due to the engagement of the roller 52 with the latch53, further facilitates the closing and locking action, and as the pin64 moves into or past dead center a-a (Figure 3), the jaws 5 and 6 arelocked positively in closed position.

I do not intend to be limited to the precise details shown or described.
